SUMMARY:MS Thesis Defense: Ms. Jerianne Bonaguidi
DESCRIPTION:Proving a Softball Pitch Can Rise Under 60mph Through Mathematical Modeling\nJerianne Bonaguidi\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nMany softball coaches claim that a pitcher cannot actually throw a rise ball under 60mph; they claim it is just a “high fastball.” This project tests that theory with a live pitcher\, calculus\, and physics equations. The major claim is that if a pitcher has a high enough spin rate\, the ball can still rise throughout its whole entire trajectory\, even if thrown under 60mph. \nAdvisor:\nDr. Gabriella Pinter \nCommittee Members:\nDr. Craig Guilbault\nDr. Lijing Sun

SUMMARY:PhD Dissertation Defense: Mr. Andrew Frohmader
DESCRIPTION:Graded multiplicities in the Kostant-Rallis setting\nMr. Andrew Frohmader\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nThis dissertation contains two main results. First\, we provide combinatorial branching rules for GL(n\, C) to O(n\, C) and GL(2n\, C) to Sp(2n\, C) extending the Littlewood restriction rules. Second\, we use these branching rules and the combinatorics of GL(n\, C)-crystals to derive a formula for the graded multiplicity of a K-type in the regular functions on the K-nilpotent cone for GL(n\, R)\, GL(n\, C) and GL(n\, H). \nAdvisor:\nJeb Willenbring \nCommittee Members:\nAllen Bell\, Chris Hruska\, Istvan Lauko\, and Kevin McLeod

SUMMARY:Colloquium: Dr. Dave Spade
DESCRIPTION:Statistical Modeling of Control of Animal Motion in Three Dimensions\n\n\n\nThis manuscript gets ahold of the control aspect of how Daphnia magna move through their surroundings in a control-type environment with still water and with no external stimuli. We present a statistical model for step lengths and roll\, pitch\, and yaw angles. We then use this model to describe a procedure for generating biologically realistic synthetic trajectories. The aim of this article is to provide a starting point for modeling animal motion in a variety of environmental settings.

SUMMARY:Colloquium: Dr. Kevin Palencia Infante
DESCRIPTION:“My Instructor Was Kind of a Computer”: Rethinking Faculty–Student Interactions in Calculus\n\n\n\n\nDr. Kevin Palencia Infante\nAssistant Professor & Calculus Coordinator\nNorthern Illinois University \n\n\n\nWhile computers and AI are playing a growing role in education\, faculty remain essential to teaching in ways that meaningfully shape student learning. In this talk\, I present findings on how calculus students experience their interactions with instructors. Drawing on a qualitative study framed by academic validation and invalidation\, Black and Hispanic students share perspectives on their classroom experiences. They highlight instructional practices that support their learning\, including collaborative environments\, clear conceptual guidance\, availability outside of class\, and actions that make them feel valued. They also point to interactions that leave them feeling unsupported or not validated. Across these experiences\, students emphasize the importance of compassion\, care\, and instructor presence. By centering student voices\, this talk shows how faculty–student interactions shape students’ experiences in calculus beyond content delivery.

SUMMARY:Colloquium: Dr. Steve Butler
DESCRIPTION:A Short Course in Spectral Graph Theory\nProf. Steve Butler\nMorrill Professor of Mathematics\nIowa State University \nGraphs are used to model relationships (edges) between objects (vertices). A graph’s structure can efficiently stored in an array format. We can go one step further and replace arrays by matrices (which are arrays with benefits!)\, the eigenvalues of these matrices tell us some information about the graph. The extent to which we can understand the structure of the graph from these eigenvalues is spectral graph theory. We will do a quick walk through of some of the flavors of matrices that are studied in spectral graph theory\, and some results that arise from their study.

SUMMARY:Colloquium: Prof. Genevieve Walsh
DESCRIPTION:Quasi-isometric Hyperbolic and Cusped Relatively Hyperbolic Groups are Symmetric\nProf. Genevieve Walsh\nProfessor of Mathematics\nTufts University \nThis talk will first describe hyperbolic groups and relatively hyperbolic group pairs\, and give some key examples. We then delve into understanding when the cusp space for a relatively hyperbolic group can be quasi-isometric to a hyperbolic group. For example\, real hyperbolic spaces admit uniform and non-uniform lattices. We show that this is the exception. In particular\, if a hyperbolic group is quasi-isometric to a cusped space for a relatively hyperbolic group\, then both groups are lattices acting on a rank-1 symmetric space. \nThis is joint work with Daniel Groves\, Emily Stark\, and Kevin Whyte.

SUMMARY:Graduate Student Colloquium: Jonathan Walker-Moses
DESCRIPTION:The Beautiful Interplay of Rotation Groups in Three Dimensions\n\nWe’ll explore the connections between the rotation Lie groups (SU(n) and SO(n)) in two and three dimensions. In doing so\, we’ll prove a remarkable theorem about the way that SU(2) and SO(3) relate using quaternions and then discuss some connections to complex analysis at the end. In doing so\, we’ll take a very fun and (in my opinion) mind-blowing journey through spheres of different dimensions. Absolutely no knowledge of Lie theory is expected and I’ll be happy to clarify any details from topology or group theory that come up that you aren’t familiar with.

SUMMARY:Colloquium: Dr. Jennifer Elder
DESCRIPTION:Doing Anything You Want With Combinatorics\nDr. Jennifer Elder\nAssistant Professor of Mathematics\nMissouri Western State University \nWhen Mathematical Reviews first launched as a journal in 1940\, combinatorics was not listed as a research area. The Seven Bridges of Königsberg was solved in 1736\, so this absence is not due to later development of the field. Combinatorics has simply been hard to define on its own\, given that it is used as a tool in so many different areas of mathematics. \nThis talk will take the opposite point of view. We will center our focus on several research problems motivated from a combinatorial standpoint\, and the connections to other fields of research. These connections can be simple\, such as bridging different subareas of combinatorics: a study of a specific set of words uncovering unexpected properties of intervals in a lattice. Or the connections can be more odd\, connecting widely different areas of mathematics: a study of braid diagrams on k strands as a dynamical algebraic system.

SUMMARY:Colloquium: Dr. Elaine Spiller
DESCRIPTION:Uncertainty Quantification for Geophysical Hazard Analysis\nDr. Elaine Spiller\nProfessor of Applied Math and Statistics\nMarquette University \nGeophysical flows — landslides\, storm surge\, tsunamis\, volcanic flows\, etc — pose a serious threat to nearby populations. Ideally\, probabilistic hazard assessments combine available knowledge about physical mechanisms of the hazard\, data on past hazards\, and any available precursor information. Systematically assessing the probability of rare\, yet catastrophic hazards adds a layer of difficulty due to limited observational data. Via computer models\, one can exercise potentially dangerous scenarios that may not have happened in the past but are probabilistically consistent with the aleatoric nature of previous geophysical behavior in the record. \nI will discuss recent work and ongoing methodological challenges toward making efficient and flexible geophysical hazard maps focusing on applications to volcanic flows (pyroclastic density currents) and post-fire debris flows.

SUMMARY:Graduate Student Colloquium: Ilana Lavene
DESCRIPTION:An Introduction to Boundaries of Groups\nWe introduce a generalization of parking functions in which cars are limited in their movement backwards and forwards by two nonnegative integer parameters k and ℓ\, respectively. In this setting\, there are n spots on a one-way street and m cars attempting to park in those spots\, and 1≤m≤n. We let α= (a1\,a2\,…\,am) in [n]^m denote the parking preferences for the cars\, which enter the street sequentially. Car i drives to their preference a_i and parks there if the spot is available. Otherwise\, car i checks up to k spots behind their preference\, parking in the first available spot it encounters if any. If no spots are available\, or the car reaches the start of the street\, then the car returns to its preference and attempts to park in the first spot it encounters among spots a_i+1\,a_i+2\,…\,a_i+l. If car i fails to park\, then parking ceases. If all cars are able to park given the preferences in α\, then α is called a (k\,l)-pullback (m\,n)-parking function. Our main result establishes counts for these parking functions via a recursive formula.

SUMMARY:Colloquium: Prof. Trevor Leslie
DESCRIPTION:Sticky Particle Solutions of the Euler Alignment system \nThis talk is about the Euler Alignment system from the field of collective behavior. After a primer on modeling considerations and the equations at issue\, we discuss the weak solution theory developed by Leslie and Tan via using a sticky particle discretization technique pioneered by Brenier and Grenier. The special structure of the equations allows us a detailed look into the time-asymptotic behavior of the system\, including the structure of so-called “flocking states”.

SUMMARY:Graduate Student Colloquium: Kushlam Srivastava
DESCRIPTION:An Introduction to Boundaries of Groups\nA key idea in the field of geometric group theory is to study geometric and topological objects associated with groups. Boundaries of groups are examples of such objects. In this talk we will look at boundaries of (relatively) hyperbolic groups and see how their topology is directly related to algebraic properties of groups. This expository talk is meant to be an entry point for the audience to explore geometric group theory and no prior knowledge except basic topology is needed.

SUMMARY:Colloquium: Dr. Joseph Rennie
DESCRIPTION:(Higher) Categorical Galois Theory for the Aspiring Mathematician \nHere we focus on the function/motivation of specific structures (most likely new to the audience) in high-level mathematics with the aim of highlighting major themes in the broader canvas of modern mathematics. Specifically\, Galois Theoretic ideas emerge across disciplines\, all as instances of a single theorem in (higher) category theory. This talk uses that idea to motivate a journey through three main themes relevant to any area: \n\nThe ubiquity of presheaf localizations\nThe concept of a classifying object\nThe pervasiveness of Algebro-Geometric duality\n\nIn some parts\, I will use categorical-theoretic language not with the expectation that people speak the language\, but rather as a demonstration of the beauty of the perspective gained by acquiring fluency. (What better way to motivate oneself to learn a new language than to listen to some of its poetry?) \nThis talk also serves as an onboarding for those interested in research projects on this topic. Though the talk should also inspire those who have no interest in category-theoretic research.

SUMMARY:Colloquium: Dr. Alison Marzocchi
DESCRIPTION:Dr. Alison Marzocchi\nSupporting Mathematics Faculty Instructional Improvement with Reflection Cycles\nDr. Alison Marzocchi\nProfessor of Mathematics\nCalifornia State University\, Fullerton \nMany mathematics faculty desire to improve their instruction but may feel they lack the knowledge\, confidence\, skills\, or time to do so. Among numerous professional development activities\, our mathematics department at California State University\, Fullerton offers Reflection Cycles\, both student-facilitated and peer-facilitated. Peer-facilitated Reflection Cycles involve pairs of faculty taking turns leading each other in three phases: planning\, implementation\, and debrief. The planning phase involves setting specific goals for an upcoming lesson. The implementation phase involves observation during a regularly scheduled class session\, with a focus on the goals set by the instructor. The debrief phase involves reflection on the implementation and setting new goals for the future. A second Reflection Cycle can then be scheduled to continue working on the same goals or to set new goals. Reflection Cycles allow for gradual\, sustained\, individualized improvement of instruction. They are facilitated in-house and can additionally improve department camaraderie.

SUMMARY:Colloquium: Dr. Daniel Noelck
DESCRIPTION:Exponential Stability Of The Discrete Stochastic Filter Via Non-degeneracy Andanalytic Stability Of The Signal\nDr. Daniel Noelck\nSenior Research Associate\nIllinois Institute of Technology \nThe stability of discrete time filters has been an active field of research\, particularly when applied to numerical filter approximation schemes. Most results in the field are obtained on a compact signal space\, but there is no reason to believe the results should not carry over to non-compact spaces. In this talk\, we will introduce the discrete time filtering problem\, discuss some well known results on compact spaces\, and the difficulties of expanding those results to non-compact spaces\, and then introduce recent results for stability on those non-compact spaces. Finally\, we will discuss the future work available in the continuous time setting.

SUMMARY:Colloquium: Prof. Greg Ongie
DESCRIPTION:A Function Space View of Neural Networks\nProf. Greg Ongie\nAssistant Professor\nMarquette University \nMany mathematical analyses of deep learning focus on how neural network (NN) parameters evolve during training. A complementary perspective is to view NN training as fitting a function belonging to a function space implicitly defined by the architecture and training procedure. In particular\, when parameter norms are explicitly or implicitly constrained\, NNs exhibit a bias toward functions with low “representation cost\,” defined as the minimal parameter norm required to realize the function with a given NN architecture. This talk surveys recent results that characterize representation cost of shallow NN architectures in terms of Banach space norms\, and through non-linear notions of function rank for deeper NN architectures. Finally\, we discuss how bias towards low representation cost functions helps to explain generalization in various applications.

SUMMARY:Colloquium: Dr. Dexuan Xie
DESCRIPTION:Recent Advances in Nonlocal Dielectric Continuum Models for Predicting Protein and Ion Channel Electrostatics\nDr. Dexuan Xie\nProfessor\nUniversity of Wisconsin-Milwaukee \nThe calculation of electrostatics for proteins and ion channels is a fundamental challenge in structural biology\, computational biochemistry\, biophysics\, and mathematical biology. Traditional dielectric continuum models\, such as the Poisson–Boltzmann equation and its variants\, are widely used for this calculation. However\, their prediction accuracy often deteriorates near highly charged biomolecular surfaces because they neglect the polarization correlations of water molecules. To address these limitations\, a nonlocal dielectric continuum modeling approach was introduced roughly four decades ago. Over the past decade\, this approach has seen substantial theoretical and computational advances\, largely driven by our group’s work under support from the National Science Foundation. \nIn this seminar\, I will present our nonlocal dielectric theory and report our recent progress in developing nonlocal dielectric continuum models and finite element solvers for proteins and ion channels. I will also compare the predictions of our novel nonlocal models with those of the traditional local models and present numerical results demonstrating the efficiency of our solvers and the high performance of our software package. This work is a collaboration with my students\, Liam Jemison and Matthew Stahl. It has been partially supported by the National Science Foundation under award DMS-2153376 and by the Simons Foundation under research award 711776.

SUMMARY:PhD Dissertation Defense: Mr. Marco Vaassen
DESCRIPTION:A Bootstrap Goodness-of-Fit Test for Parametric Survival Models\nMr. Marco Vaassen\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nIn many scientific disciplines\, finding a suitable model compatible with real-world observations is the basis for statistical inference and prediction. In survival analysis\, this task is further complicated by censoring. This dissertation introduces a new bootstrap approach to goodness-of-fit testing for parametric survival models\, based on the Kaplan–Meier process with estimated parameters. The test statistic compares the nonparametric Kaplan–Meier estimator to a fitted parametric model\, quantifying deviations from the null via functionals that yield Kolmogorov–Smirnov or Cramér–von Mises-type tests. We establish the asymptotic correctness of our method by showing that the original and bootstrap test statistics have the same weak limit under the null. The result is a consistent\, easily implementable framework for assessing model fit in censored settings. \nAdvisor:\nProf. Richard Stockbridge\, Prof. Gerhard Dikta \nCommittee Members:\nProf. Richard Stockbridge\, Prof. Gerhard Dikta\, Prof. Chao Zhu\, Prof. David Spade\, and Prof. Vincent Larson

SUMMARY:Colloquium: Prof. Christian Wolf
DESCRIPTION:  \nMeasures of Maximal Entropy on Coded Shift Spaces: Uniqueness and Computability\nProf. Christian Wolf\nExecutive Officer and Professor\nCUNY Graduate Center and City College \nIn this talk\, we present results about the uniqueness and computability of measures of maximal entropy on coded shift spaces. A coded shift space is defined as the closure of all bi-infinite concatenations of words from a fixed countable generating set. We derive sufficient conditions for the uniqueness of measures of maximal entropy based on the partition of the coded shift into its concatenation set (sequences that are concatenations of generating words) and its residual set (sequences added under the closure). We also discuss flexibility results for the entropy on the concatenation and residual sets. Next\, we present a local structure theorem for intrinsically ergodic coded shift spaces\, which shows that our results apply to a larger class of coded shift spaces compared to previous works by Climenhaga\, Climenhaga and Thompson\, and Pavlov. Finally\, if time permits\, we discuss the computability (in the sense of computable analysis) of measures of maximal entropy for coded shift spaces. The results presented in this talk are joint work with Tamara Kucherenko and Martin Schmoll. \n  \n

SUMMARY:Colloquium: Prof. Yangjin Kim
DESCRIPTION:Cytokine Shield Formation in Tumor Growth by Blocking Chemotactic Migration of T Cells in Response to CXCL12 from Senescent Tumor Cells\nProf. Yangjin Kim\nProfessor\nBrown University \nCellular senescence can induce dual effects (promotion or inhibition) on cancer progression. While immune cells naturally respond and migrate toward various chemotactic sources from the tumor mass\, various factors including senescent tumor cells (STCs) in the tumor microenvironment (TME) may affect this chemotactic movement. In this work\, we investigate the mutual interactions between the tumor cells and the immune cells (T cells and macrophages) that either inhibit or facilitate tumor growth by developing a mathematical model that consists of taxis-reaction-diffusion equations and receptor kinetics for the key players in the interaction network. We first apply a mathematical model to a transwell Boyden chamber invasion assay used in the experiments to illustrate that STCs can play a pivotal role in negating immune attack through tight regulation of intra- and extra-cellular signaling molecules. The mathematical model consists of a system of parabolic-hyperbolic PDEs with two separate model domains based on experimental setting empirical data. Neuman B.C. on the outer boundary and Interface B.C. from homogenization of holes of various sizes on porous membrane are assigned. In particular\, we show that senescent tumor cells in cell cycle arrest can block intratumoral infiltration of CD8+ T cells by secreting a high level of CXCL12\, which leads to significant reduction its receptors\, CXCR4\, on T cells\, and thus impaired chemotaxis. Macrophages also play an important role in mediating or inhibiting given signaling pathways between different cells in TME. The predictions of nonlinear responses to CXCL12 were in good agreement with experimental data. We tested several hypotheses on immune-tumor interactions under various biophysical- and biochemical- conditions in the tumor microenvironment and developed new concepts for anti-tumor strategies targeting senescence induced immune impairment. \n

SUMMARY:Colloquium: Prof. Caroline Terry
DESCRIPTION:Measuring Combinatorial Complexity via Regularity Lemmas\nProf. Caroline Terry\nAssociate Professor\nUniversity of Illinois-Chicago \nMany tools have been developed in combinatorics to study global structure in finite graphs. One such tool is called Szemerédi’s regularity lemma\, which gives a structural decomposition for any large finite graph. Beginning with work of Alon-Fischer-Newman\, Lovász-Szegedy\, and Malliaris-Shelah\, it has been shown over the last 15 years that regularity lemmas can be used to detect structural dichotomies in graphs\, and that these dichotomies have deep connections to model theory. One striking example is a dichotomy in the size of regular partitions\, first observed by Alon-Fox-Zhao. Specifically\, if a hereditary graph property H has finite VC-dimension\, then results of Alon-Fischer-Newman and Lovász-Szegedy imply all graphs in H have regular partitions of size polynomial is 1/ε. On the other hand\, if H has infinite VC-dimension\, then results of Gowers and Fox-Lovász show there are graphs in H whose smallest 1/ε-regular partition has size at least an exponential tower of height polynomial in 1/ε. In this talk\, I present several analogous dichotomies in the setting of hereditary properties of 3-uniform hypergraphs.

SUMMARY:Colloquium: Dr. Suzanne Boyd
DESCRIPTION:Polynomial-time Computability of the Julia Set for Polynomial Skew Products of Two Complex Variables\nDr. Suzanne Boyd\nAssociate Professor\nUniversity of Wisconsin-Milwaukee \nIngrained in the modern study of dynamical systems is the use of computer experiments for revelation and illustration. In this talk\, I will explain a polynomial-time computer algorithm for approximating the Julia set of a polynomial skew product of two complex variables. I will begin by defining the involved terms\, including computability\, Julia set\, and polynomial skew product. This work is joint with Christian Wolf. It relies on some my previous work on designing and implementing rigorous computer algorithms to confirm results of the experimental observations on the dynamics of polynomial maps of two complex variables\, including polynomial skew products. These algorithms are designed to locate a neighborhood of the chain recurrent set\, build a model of the dynamics of the map on this set\, and attempt to determine hyperbolicity (or Axiom A) of the map on its chain recurrent set.

SUMMARY:Math Community of Practice: Let's Talk About Math Anxiety
DESCRIPTION:Math Community of Practice: Let’s Talk About Math Anxiety\n\nAccording to a March 2024 US News survey\, most college students report struggling with mental health issues. Given that mathematicians are typically not mental health professionals\, knowing how to address this in the classroom often falls outside the scope of our expertise. This session will introduce participants to the concept of math anxiety\, a mental health issue that affects how students perform in our classrooms. Participants will learn about the condition\, dispel some common myths and rumors about mental health in the classroom\, and leave with a list of research-supported interventions they can try in their classes to support students with math anxiety without sacrificing content or rigor. \nFacilitated by Beccah MacKinnon
